Abstract (en)
An electrically-controlled force-exerting actuator com<sub>-</sub> prising a force-applying power spring (1) arranged to exert a force on an output member (5), a force-applying control spring (10) arranged with respect to the power spring (1) such that the force exerted by the control spring (10) is detracted from the force exerted by the power spring (1) to determine the residual force exerted on the output member (5) by the power spring (1), and an electric motor (14) operable to vary the detractive force exerted by the control spring.
